LOCK.

Application filed February 1, 1919.

To all whom t may concern.'

Be it known that I, SAMUEL Il. TERRY, a citizen of 'the United States, residingA at Chicago, inthe county of Cook and State of Illinois, have invented certain new and useful Improvements in Locks, of which the following lis a specification.

This invention relates to locks.

It relates more particularly to automobile Vsteering wheel locks.

The invention will be explained as embodied in a steering wheel of the type where,- inthe gas and spark control levers are above the wheel, although it is applicable to other types of steering wheels.

`One of the objects of the inventionv is to provide an improved lock for protecting automobiles against theft.'

.Another object is yto provide a steering Wheel lock which may be readily` installed but can not be readily removed after in,- stallation.

Another object is tol provide a steering wheel lock wherein the locking mechanism is f vhoused and protected against removalA by the hub of the wheel.

Another object is to rprovide a steeringr wheel lock which is vsimple and Vrelatively reliable and inexpensive.

Other objects and advantages will hereinafter appear.

An embodiment of the invention is illustrated in thev accompanying drawings, wherein.-

Fig. 1 is a central longitudinal section of the device taken online 1-1 of Fig. 2 showing-the `wheel locked to the steering post.

Fig. 2 is a transverse section taken online 2-2 of Fig. 1;

Fig. 3 isa section taken on line 3--3 of Fig. 2.

Fig, 4 is a section taken on line 1-t of Fig. 5,'and

Fig. 5 is a section, similar to the section f shown in Fig. 1, and which shows the steering wheel unlocked or inra position relatively rotatable with reference to the steering post.

In all the views the same reference characters are employed to indicate similar parts. The steering wheel chosen for illustration is of thev type wherein unauthorized use of the automobile is prevented 'by allowing the steering lwheel to befturned idly or inopera' tively relative to, the steering gear. Au-

Serial No. 274,469.

thorized use of the automobile is permitted l by operatively associating the steering wheel and steering gear. t

The automobile steering wheel 1 is adapted for mounting upon the top of the usual steering post or shaft 2. The outer rim of the wheel is not shown, but it may be of any approved type.

vPost 2 is ordinarily housed within a stationary steering column 3. In automobiles wherein the gas and spark control levers are above the steering wheel, the steering post is usually in the form of a tube Aand survlie above the plane of the center of the steering wheel and cooperate with a quadrant 9 in the usual manner.

A journal-collar or journal-head 10, in the general form of a sleeve, is provided for relatively rigid attachment topost 2. rI he bore of head l0 and the upperend of post 2 may be correspondingly tapered to provide a tight fit therebetween. The head and-post also may be keyed together by keys 11 to prevent relative rotation when they are properly assembled. A suitable holding device, such as a nut 12 adapted to be screwed upon the reduced and externally threaded upper' end 13 of post 2, may be used to securely anchor or hold sleeve 10 and the assembled wheel upon the steering post,

The central portion of the steering wheel spider or hub 14 is made somewhat cupshape to form a housing or casing for sleeve 10. The lower endl of hub casing 14 is internally threaded. Sleeve 10 forms a journal-head upon which the steering wheel may be freely and idly turned without operating-the steering post, as will be hereinafter described. Sleeve 10 and hub 14 are rotatably secured together but held against relative longitudinal movement by suitable means, such as pins 15. Pins 15 are insertable into suitable openings in hub 14 and lie in an annular or circumferential groove 16 in sleeve 10. A ring or washer like plate 17, whose periphery isthreadedto enter the internally threaded lower end'of hub 14,

llU

' steering Wheel. lWhen latch-bolt 21 is ce j moved` into one of the sockets 20,)the steering Wheelis immovably locked to the sleeve and, Consequently, to the Steering poet and steerinagear- The automobile is then in manageable condition because turning the steering `Wheel turnsvthe steering gear` andA guiding Wheels.

When lach-boit 21 is withdrawn from hubk 10, the steering Wheel is freed from the steering post and, may be turned independently thereof. In this condition the automobile is unmanageable because the turning of the steering Wheel does not turn the steerin gear and the guiding Wheels.

latch-bolt 21 is slidably carried in a suitable recess in hub 14 and may be' moved by y suitable'mea'ns such as an ordinary pin and tumbler key-actuatedilock 22. The key actuates acrank arm 23. Crankarm '23 ts into anf annular groove 24 in latch-bolt 21 so that the rotation ot the key causes reciprolcation ofthelatch-bolt in the usual manner.

Thefl'atch-bolt may be biased to locking position relative to sockets by Ya spring y25. 'The steering vvheel lock herein shown is installed as o-llovvs:

If ythe installation is to be' made on an automobile alreadyequipped with an ordinary Wheel, the old Wheel is first removed.

Of course, for'factory installation, `the automobile ma-ynothave 'a Wheel in place.

Plate 17 is slipped down' over the top of the steering post. Journal head 10 is fitted upon the top of the steering post andthe securing device therefor, such as n ut 12, is applied. The steering wheel hub 14 is then set down upon the journal head', pins 15 are driven injtoI place through the hub and groove 16 andplate 17 is raised and screwed and fastened in place in the bottom of` the hub. If the automobile is of the type having the spa'rk and gas control levers above the steering Wheel, these appliances and the quadrant are appliedin the usual Way.

The automobile now may be rendered manageable by operating the lock, so that the latchfbolt is in one of the journal-head sockets.` In order to( render the' automobile unmana eable, the lock is operated to raise the lato -boltffrom the socket and thereby free the steering Wheel.

Thecentral portion or hub of the steering axis a housing which en'closes and journalsl` on the head and also prevents access to the nut, lock mechanism for operatively connecting and disconnecting the Wheel Yand head, and mea-ns for preventingr the removal j of the housing from the head.

2. An automobile lock a journal head adapted for operative association with the steering post of an' automobileand providing a bearing for a. steering ivlieel, ai nut for preventing the removal of, a head.

from the` ost, a steering vvheel havi'nfa housing W ich encloses andv is journ'lcd upon the head and also prevents access to the nut, lock mechanism for oplerativelyand inoperatively associating the4 lhead and Wheel, and means` for holding the 4steering Wheel on the head. l Y

3. An automobile loc-k comprising a journal head adapted for attachmenty tothe steering post of an autonoobfile`and` having. sockets therein, a nut adapted to be screvyed upon the steering post andi acting to'hold the head thereon, a steering vvheel y'Whose hub is journaled upon the head and forms'a means for preventingy accessif Y the, nut, and a manually controlled latch-bolt. carried by the Wheel and movable into andfout'offa socket in the-head to operativelyl connect to disconnect thel vvheeland head.

4. An automobile lock having, journal head tor attachment to the steering post oil an automobile; a nut for application tothe post tohold the head,y thereon;` a steering wheel having a housing which installed.y
